Sifus-sifus sekalian, need some help regarding my iphone. 

iPhone Generation : 3G 8G
Unlocked? (or Part Number): Official Unlocked (S'pore set)
Current Firmware : 3.1.3 (7E18)
Current network: Celcom (P148 data plan)
iTunes Version : 9.0
PC/MAC : PC
Jailbreaking software : Used to JB using quickPWN (b4 v3.1.3), now tarak JB

Problem Encountered :
Iphone will lag on several occasions such as:
- When clicking on 'Home Button' and slide to unlock , the "Slide to Unlock" slider will hang for a few seconds b4 responding.
- Keyboard will lag when typing SMS.
- Lag when sliding apps from left to right (and i have only 3 pages )
- Lag when closing apps.

its a 3G, not a 3Gs of course slow la, it will be even more evident when you put lotsa stuffs in
I have been saving my SMS since 1/4/08, mine is as slow as it can get but i don't mind

Another (even worse) problem is the dropped calls and incoming call failure problem.
- Calls will drop suddenly when on the phone (mostly when just pick up - sometimes tak sempat say Hello sudah drop >< )
- Incoming calls cant get thru A LOT of times. Friends and family describe as  - when calling me, no dial tone. Have to try a lot of times baru get thru.
- SMSes will only reach me a few hours after ppl send, sometimes wont receive.

either signal chip problem or antenna faulty. Most probably occurs when you slipped the phone into some water or something.
T_T HELP!



2. My HOME button is kinda insensitive (not responsive). Is the problems all bcoz of this?

Wear and tear la bro, mine is as insensitive as it gets.
