iPhone Generation : 3GS
Unlocked? (or Part Number): Maxis
Current Firmware : 3.01
iTunes Version : 8.2
Jailbreaking software : No
Problem Encountered : Just wan to inform, i dont have any problem on my phone.

I have noticed that i3GS reception worse on 3g than edge/gprs signal.. the signal bar very low between 1-2 bar.. but full strength when i turn 3g off. Especially when you hold the phone(right hand), the 3g signal from 4-5 bars dramatically drop down to 1 bar in few seconds.. when i put down the phone back, the 3g signal going up again.. however, this is not effecting to edge/gprs signal when u hold the phone.

Steps Taken So Far : Try Maxis and Celcom, same result.. Test at Sg Buloh and Bukit Jalil, same result.. OS 3.0 and OS 3.01 same result..

i have used australian 3GS unit before for a week, same result.. 50% low strength and 50% good strength bar.. try it ur self, put ur phone down and when the signal going tu 4-5 bars, take and hold the phone(bottom to half), use ur right hand and wait for few seconds.. make sure u turn 3g on..

i found a solutions how to enable maxis mms for OS3.1/MAXIS 5.0 ..

1. Power off 3gs
2. Switch to non maxis sim card
3. Turn on 3gs and go to General>Network>Cellular Data network> Leave Blank all field except 2 below:
- MMSC: http://172.16.74.100:10021/mmsc
- MMS Proxy: 202.75.133.49
*You will see the MMS Proxy: 202.75.133.49:80 (remove the red)
4. Return back to Home Screen and power off the 3gs
5. Switch back to maxis sim card and Turn on
6. That's it.. it work for me

If your dont have other telco sim card, maybe u have to full restore your 3gs.
