In I5500XWJJ6 firmware there isn't option to turn off data connection like in stock firmware (at power off screen or under setting > wireless & network > mobile network: enable always-on mobile). There is a solution for that however: use APNdroid (search at the market). It works by renaming APNs string in setting. In conjunction with 3G watchdog to monitor your data usage, you can effectively control your data usage automatically.

I like I5500XWJJ6. Rock solid and stable. But at the end of day, I flashed my phone back to I5503DXJG5 as soon as it's available at samfirmware.com I need indonesian swype (though with your help I can make one for I5500XWJJ6), and DioPen Chinese IME keyboard (learning chinese right now). I restored my full backup from titanium backup without a hitch, all apps, settings, and data were preserved perfectly! For those who don't know how to do full backup using Titanium backup, press menu, batch, run backup all user apps + system data.

Benchmark results:





Neocore shows that eclair already handles gpu acceleration as good as it gets.

Speed Pi shows the benefit of JIT on cpu extensive task, more than twice as fast!

Quadrant mix bench cpu and gpu benchmark shows modest 22% overall speed improvement.


Flashing notes:

- Flashing this firmware does not erase your data, but apparently the new swype that comes with the this firmware conflicts with the old swype and causing the phone to periodically vibrating. It also eats cpu cycle thus makes the phone lagging as hell. Instead of getting Froyo (Frozen Yogurt) you get Fropho (Frozen Phone) So first, you *should* force stop swype: settings > applications > manage applications > press 'All' tab > Swype > Force stop. Beyond this point I have no solution yet beside hard resetting the phone. But by hard reset, everything will be gone, and if you don't have backup.. So before reset, look around, do benchmark, etc. Most importantly, don't you think it's a good time to root the phone and install Titanium Backup?

- If you are prepare like me and have backup, good on you But don't forget, before restoring everything, uncheck swype so it won't be restored.

Thanks bro gocke for clarifying it to sgpc 3g watchdog is a nice utility to have. Here in Indonesia using Telkomsel we have quite cheap data plan rate, RM 35 / month for unlimited, up to 384 Kbps (512 Kbps in practice) HSDPA connection. So I've been using my G5 as wifi tether, and 3g watchdog helps me keeping track how many data I've been using so far. Speaking about tethering, I could not get the new froyo build-in wifi tether to work. It works as a wifi router in infrastructure mode (i can access other computers in LAN), but there is no internet access. So I am still using barnacle for tethering, which still works perfectly (in froyo I need to turn on option 'skip wpa supplicant' in setting). What a pity, as the build-in tether can work in infrastructure mode and wpa2, and barnacle can only operate in ad-hoc mode and unsecure wep128. Do you guys have any luck with the build-in wifi tethering in froyo?

Thanks fyi bro. I knew there must be something wrong with my setup because skype and torrent work with froyo's build-in, but not browsing. And this happen to all five of my computers at home. Barnacle gives me zero problem, I can connect all five of my computers at the same time without problem whatsoever. I feel hard reset and starting fresh without restoring backup (especially apps) would work.. but.. Maybe if I have a lot of free time some day. Right now I pray that no neighbour of mine is skilled enough to crack the barnacle's wep encryption

That's ok ngpc, thanks anyway. I think 'n'(ice) word is more appropriate for you than the 's' word Ouch... so expensive eh.. I've just check out the maxim, celcom, and digi's data plan, and you're right they are pricey. Here with my operator I can buy daily data plan if I want to, only RM 1.7 / day unlimited usage. There is quota of like 15 MB before the speed is supposedly dropped. But fortunately that is not enforced, so I can dowload more than 1GB per day with less than RM 2 Btw, do you guys know that while dowloading I can still use G5 for voice call and sms without interruption? Galaxy 5 is without doubt the best handset I have ever own.

Have a nice weekend guys!

Nice summary sgpc. I agree and would like to add one more.

Connectivity - Froyo.

The the portable wifi hotspot feature elevates froyo to a new level. When I used Barnacle wifi tether for the first time, I was like "wow, now a phone can emulate wifi router?" Not perfect, you can't connect other phone to G5 in ad-hoc mode for example, but amazing still. Now the froyo's build in wifi tether that works in infrastructure mode as opposed to ad-hoc mode in barnacle, complete that illusion. It's a feature that is very handy and also will no doubt impress a lot of your friends. OK, perhaps unlimited data plan is still very expensive in most countries, and wifi tethering is a cool feature but has no practical use for those people. Now look at the wifi router feature and consider these scenarios:

1. Want to transfer large files between laptops but no one has flashdisk large enough? No problem. Transform your G5 into router and send those files away up to 20 meters or more, at about 1.25 MB/s transfer rate in my case.

2. While you are waiting for the transfer to finish, you and your friend(s) want to play a quick LAN games? Done!

3. Sharing a printer? Yes.

Etc, you get the idea, basically every benefit that a router has.

PS: Just an update to my situation. It turns out the source of my problem is that my operator (telkomsel) is blocking tethering when using froyo's build-in. I tried using other mobile operators (indosat and xl) and wifi tethering worked like charm. There is no problem in using barnacle. So next time if you guys are having problem wifi tethering with froyo's build-in router, you might want to point finger to your operator before blaming your setup.
