Yes, thank you for this thread. It is extremely helpful. I have sent a few Noobs here to find answers to their qustions. Too bad they didn't try to find it on their own first.

Performance tweeks I've learned since I installed this update. You must be rooted to do this....
TO SPEED UP PHONE AND BOOST PERFORMANCE.

1. Use titanium backup or the app of your choice to freeze or uninstall unwanted or misbehaving apps. You can find a list of apps that come preinstalled (bloatware) that is known to be safe to freeze or uninstall by searching the dev section.
2. Uninstall any and all task killers or task managers. After research I find they do more harm and slow down performance and kill battery life than they help. By freezing or uninstalling misbehaving apps in step one you don't have to worry about apps running in the background eating up your data. And besides ics has a really nice data manager built in.
3. Install apex launcher from the market. I can't explain why but using this launcher with ics instead of the stock tw launcher sped my phone up considerably and totally eliminated that little bit of lag that was in it when exiting apps and scrolling screens. Not to mention apex has a lot of freeking really cool features you can't do with the stock tw launcher. Like add another shortcut icon on the dock bar and the ability to scroll 5 dock bars full of shortcuts you can add. And the home screen allows for another whole row of icons and much much more. But best of it made my phone ALOT FREAKIN FASTER....

BATTERY DRAIN ISSUES.
I found going from gingerbread to ics was a bigger strain on my battery a way bigger strain. So far this trick has helped a lot but I'm still looking for other ways to go with this to improve it even more. So if you have any tricks up your sleeve feel free to post please. So here is what I've found so far...
I used rom manager from the market but I'm sure there are other free apps that can do this again far as I know you need to be rooted to do this...
1. Wipe battery stats. After installing any new rom or even updating an existing you should always wipe battery stats. This helped my phone tremendousley.
2. Find a app that monitors your battery stats. I use badass battery monitory. I don't like the name but it will tell you which apps are draining your battery and allow you to make necasarry changes. There is a free version on the market but I'm using the paid one.
I posted this info I've learned to maybe help someone else. It helped my phone a bunch but each phone is different and what works for one may not for another so I make no guarantees. For info on rooting see the link at the beginning of this thread it worked for me. Anyone that has learned other tweaks please post. And if this is in the wrong section I'm sorry. I just started using the app and not my pc to access xda and I'm trying to figure the app out still which is laid out weird and the search option just plain sux...

I'd say the issue would be ROM dependent. Your best bet is to find the thread for your current ROM, do a search on bluetooth to see if anyone has mentioned the problem.

If not, try posting your issue with as much detail as you can about your phone and situation. Someone may be able to help you there. If not, you can try PMing the dev that works on your ROM about it.

Good luck!

Do you have to have the touch version cwm in order to flash ICS? Or can the original one work (the one posted in the other sticky)? I ask as I see a lot of devs stating to use the cwm touch versions.

No you don't have to. I started the first ICS leak and had regular CWM recovery and flashed multiple ICS roms. I only recently changed to Touch for Sky ICS because it was Seanz recommendations.

But I've also read that it doesn't make a difference and in some cases that regular works better. Then again it might be Rom dependant/updater script dependant.

Before starting the procedure, I have few newbies question. I do have flashing experience (windows mobile) and have read many different forums also. Just few queries before I start the actual procedure:

1) Do my phone need to carrier unlocked before rooting?
2) Are the flashing steps in this order?

Step 1: Root the phone
Step2: Install the Custom ROM

or do I need to update Radio and Kernel also?

thanks

1) No, I never unlocked my phone, I just went out of the box -> root right away.

2) Yes that is the procedure, but to be a little more specific:

• Yes the first thing you'll have to do is root your phone.
• Once rooted, download ROM Manager from the Play Store
• Use ROM Manager to flash Clockwork Recovery (Choose T-mobile SGS2)
• Once you have Clockwork recovery you can flash a Custom ROM

Oops, I forgot to reply about your Kernel/Radio question. Most custom rom's do not include a Kernel/Radio when you flash it. They are usually separate which means your kernel/radio will stay the same most of the time (ROM Dependant, in which it should state in the OP if it does include a Kernel/Radio or not) when you flash a ROM.

Instead, you can find various kernels and radios separately that may be flashed. Make sure they are compatible with the phone and OS version. There are GB kernels/radios, and ICS kernels/radios.

Read carefully before acting!
