Dear all, need some advice here.

Phone Generation : Iphone 3g, 8GB , about 4 months in age
Unlocked? (or Part Number): Singapore/singtel official unlock, MB489ZA
Current Firmware : 3.0
iTunes Version : 8.2.1
PC/MAC : PC
Jailbreaking software : redsn0w 0.71

Problem Encountered : Can't connect to my office WIFI (using WEP key)
1. Prob persists since it was on 2.2.1 FW. After upgrade, still have problem to connect to my office network. Error "Failed to Joined".

Steps Taken So Far :
1. Respring
2. Reset network connection
3. Reset all connection
4. Restore
5. Insert IP / Gateway etc manually.
6. Upgrade from 2.2.1 to 3.0

Extra info:
1. I can connect to my home's wifi (using WPA key) with no problem. Also can connect to several others free wifi.
2. Another iPhone (with OS 3.0), have no problem to connect to the office's wifi.


So what's wrong here? what should i do? Is there any solution/patch or Do i need to reclaim the warranty? (since early next month will be going to Spore~)
