That bumper is smexy! Do you mind sharing the link? I can't seem to find the thread you're talking about.. hmm.
I got one finally sir, all thanks to you! And yes, it is very powerful! I especially like the auto correct ability after some time of usage-- very precise. But is it normal for the keyboard lagging to key in my words or is it that I type too fast? Cause I checked running apps and all but all other aspects when it happens but the phone seems to run very smoothly other than the input while I'm typing.
Super true. My sister played with my Z30 and she kept swiping up and around on her S4 later on, and got frustrated on that too,ha! She's also starting to "jokingly" hinting of how I should pass her my Z10 or my Z30. As if! Anyone who lets go of their z30 is.. Uhm, rare, I guess. I also find it harder to use back button and such when I'm already too used with dancing my fingers up and around between apps. Also, I don't need too much apps. Those I need are already in BlackBerry World and the few extra from android I can easily side/download with the Web browser. I never used that much plethora of apps even on android anyways.

my previous BB no physical keyboard.. maybe i miss the surfing/browsing experiences... nothing can beat BB, seriously..

somemore, even with 256mb quota, i download movie or everything on net but i never used more than 5mb/month..

For what i read, sure cant support..even you subscribe the bis, it will eat your data like normal plan..no data compressing bla bla bla..

but maybe otai2 got trick..

You know, if you can really do that, I'm surprised. because if you can do that, that means you've just done something BIS was not invented for.

yeah maybe sifu2 here got trick.. will check on it..
u mean, all usage data will count using BIS? 

No. erm.. how should i Put it.
like this:
phone ---through BIS----> BlackBerry NOC -----internet-----> SERVER ----through internet--> BlackBerry NOC----through BIS----> phone
That's the picture I want you to understand.
Normal phones just connect to the internet. No BIS, no NOC. No security, no compression.
In your case, the video you downloaded should be charged under your data usage, BIS or not. However, that did not happened. For example:

100mb video that goes through BIS = 95mb in size (compressed, but only smaller)
100mb video that goes through normal internet = 100mb in size.
In your case, you claimed that your usage is 256mb per month. But after downloading a lot, you only used 5MB.
That's a lot of savings, and that wasn't what BIS was designed for.

That is why I'm surprised.

Is it an old BIS plan?

On the lag when typing, I suspect its the processor not giving the OS enough power. If you just switched in from another platform (as in the phone's new, and you just jammed in everything you could find on the blackberry world + snap (google play) and all the contacts sync, etc... You may need to give it a few days, probably more if you're a super heavy user, for the OS to settle down. This is often true after OS updates / new OS installs.

The latest OS 10.2.1.3175 would eliminate this (the so called keyboad lag), because its tuned to give more processing power on all apps.

wow.. now only i know what BIS is.. hahaha

my last BIS subscription was dec 2013.. im using celcom RM25/month.. i notice my data will reduce when i stream youtube.. other than that, my data will remain the same..

p/s im prepaid user

I get your point. I had lots of friends who just took the 25/month plan and use their Blackberry's for everything- communicate, stream, tether. Turns out even if over limit they just slow it down a bit. Perfect plan for students eh  and then they just buy small android phones for instagram etc using wifi.

now got z30..
im coming the hub..

have you updated to latest OS?

and have you tried SNAP? (its for Android apps)

how's your Z30 treating you?

How much is a new Z30? Thinking of getting a backup unit.

Yeahh updated to 10.2.1.xxxx..

Snap not yet..currently outside...showing around my friends..hahahaha

My friend test and said the voice call is really clear than his htc..

What's the best price for Z30? Where to get? I'm tired of my S3. Super dumb for a smartphone.

Have anyone seen the new Passport and Classic? I love my Z30, but considering I'm typing so much on my phone, the wide Passport might feel a little bit more comfortable to hold while typing! I am so eyeing Passport!

I heard the keyboard is touch sensitive, no idea how is that going to work 

download snap.., and your blackberry experience will become wild! wild as in wild partyyy!!

i got snap last month.. and have been smiling ever since.! it's very easy.. get the step from crackberry... just use the chrome extension.. load snap.! voila..!

now you can use - maybank2u.., book cinema ticket using gsc.., MAS ticket, get access to lowyat.net forum directly! .. and all other ebanking and mobile stockbroking from your z30.!

best of all.. you don't feel any slowness at all!

the more reason.. why z30 is great phone.! battery last 1.5days..

happy with my Z30., infact bought 2-3 more for family members to be on same device!

now planning to upgrade to 10.3
