Question

2) Should I preserved baseband?
3) Anyone have the same spec with me upgrade to IOS5 without any problem of push notification and working carrier?

Dam true,

but I heard from somewhere forum folks discuss

3gs 6.15.00 must be careful do not restore with fresh IPSW,

can try with custom IPSW, pwned into DFU mode, and then iTune restore, When goes to set up iPhone during Location service > Off

They said the rest should be fine, I don't have the guts to try.

Afterward the GPS still not function-able.

Unfortunately I'd been more then half year waiting dev to provide best method to downgrade baseband.

does any try IOS5.01 beta for iphone4/4s ?

It's been few days using 4s with IOS5,

battery drain very terrible,

First day try discharge until 0%, then full charge again leave it overnight. Afterward try hard re-set.

Previous IOS5 battery drain it's very fast, currently IOS5.0.1 will summary by tonight.

Usage time always half of stand-by time, let said 5 hours of usage/ 10 hours of stand-by. Only mirror reply sms and few call, safari. Total usage not even using more then 2 hours.

System services > ALL OFF
Carries > Automatic
Notification > Several needed, fb, sms, phone etc.
Email 4 account > Push OFF, ALL manually
Phone > SIM pin OFF
Apps > Close everything in background while not using

So far testing summary

Previous iPhone4s iOS5.0, on the phone wifi upgrade to iOS5.0.1 Problem battery drain fastest
My Usage 4 hours, stand-by 8 hours.
I have no idea why usage 4 hours, fully calculator i'm using half hour only.

Currently
iPhone4s, Fresh upgrade to iOS5.0.1 852MB File
Tomorrow will update.

So far i had try this method but didn't work on iphone4s 5.0.1

Notification > On Phone, SMS, instagram, Messenger.
Location Service > On maps and Siri & Off all system services except Cell network search
Carrier > Automatic
Diagnostics Usage > Don't send, happen to me Low battery log crash
Siri > Off Raise to speak
Network > Off Ask to join networks
Restrictions > Off Ping
Date time > Off set Automatically
iCloud > Off
4 Email account with manual settings

Try drain it 0% shut down itself, and charge to 100% during midnight.

I never use the phone, but Usage always show half more then Standby time

What do you think? I heard from Apple Support Commutation,
Facebook app drain alot juice, Or sim card problem?
