No. Am I suppose to?

well im not mistaken there was someone who posted about meddling with the Digi APN settings for the 3GS cause he had the same issue after upgrading to iOS4.. try searching a few pages back

or worse case do a complete restore..that should solve it for you...

by the way is it just me noticing that the majority of Iphone Owner that has issue's with iOS 4 after upgrade are the ones that J-Bed their units?

in any case...just make sure to restore your phone back to the Original state, delete all the Cydia apps before contemplating to update to iOS4 no doubt it worked for some flawlessly where their JBED phone's was updated to v4 without issue's but it seems the one's with issue's outnumber the one's that dont...

My point is :

if J-BED = RESTORE to original version before update
non J-BED = Update away, no backup / restore needed, everything will be there once the OS completes the install. plus iTunes does backup automatically

after about 2 days using OS 4 on my 3gs,imho i can say tht its not worth to upgrade to 4 frm 3gs unless u rly can afford it

with os 4 on 3gs,the only thing diff frm iphone 4 is the screen,design,vid call,camera and the added gyroscope.performance wise can't say much yet bcoz some apps haven't rly utilized the multitasking but so far the impact is minimal,same goes for batt life

but for 3g users i can say its rly a nice upgrade

Restore as in reinstall to 3.1.2? Because ingot my iPhone running at that version when I first bought it

I would like to share my experience.
I have JB 3.1.3 and direct update without restore. After that the MMS option is totally missing in my phone and i cant online by using cellular data. Calling and SMS is working fine.
I have back up while it is still 3.1.3

However, after i restore it back to original setting(IOS4), the MMS came back and i can online flawlessly. We have to choose either setup as new phone or restore from back up after the restore, i have chosen restore from back up and the same problem happened again.

So now just back up your contacts,photos, notes before your set up as a new phone. And then sync them back.

Guys wanna ask some question.. I already upgraded to ios 4.. And im usibg maxis 3gs.. But cant find the apn setting.. Am i suppose to wait for maxis ipcc or its already there when i upgraded to ios 4..?

just plug in your iPhone into iTunes after the update and iTunes will pull down the IPCC.

you only need to manually key in APN for those telco who are not iPhone partner

here it is.. those on 3g better stay off.. use the older version.

Let say I just bought a brand new 3GS. Never jailbreak or what.
Should I go for iOS4?

Becoz you are under the official carrier which do not require you to manually setup the APN.

If you die die oso wan to setup pls go to your safari and browse this site and setup your APN manually.

After a few hours of OS4 usage,can say that its pretty cool.The folder option is handy and keeps all your apps neat and tidy.The ibooks is ok,but how many ppl read books nowadays.Other than that ,the rest is pretty same,just that on 3GS,there is a tiny bit of lag compared to the 3.1.3 version.It is quite noticeable.

Yah like Barteria, want to get comments from those on iPhone 3G running iOS4. Some comments say whole phone become very slow while some say its ok.

i just finished clean/factory restore my 3g to iOS4. super smooth n faster than ever. seriously guys. i tried everything, nothing shows any signs of lagging.

haiz... for my iPhone 3G, the update made my phone super sluggish. The phone gets EXTREMELY sluggish when i play my iPod while i SMS or check my facebook... im going back to iOS 3...

How to go back OS3 from iOS4? learning hehe

@meon55
i think you have some old non-Apple files in your backup. cos I updated mine, and its smooth
feels like a new phone again

I JB-ed my 3gs before..And now i shud restore before update (seems to be a safer way beside straight update).Restore means to os 3.1.3 or ios4 ?

yeah, same goes here and i think so too. but i don't know the solution. try identifying your particular problem (like which app is lagging) and google it?
