Guys,

I am new to this forum. I have looked at various posts but couldn't find an answer to my question, hence posting a new reply.

I bought an unlocked iphone 2 years back from a guy in New York. I am using Tmobile service and never had any problem. About my phone.

Version: 2.2 (5G77)
Carrier: Carrier 2.9
Model: MB046LL
Modem Firmware: 02.28.00

The reason I would like to upgrade is due to lack of apps that support OS lower than 3.0.

I have cydia installed. Not sure what it does!

I would like to upgrade to any version higher than 3.0. Please tell me the steps or point me to the right post. Any help is highly appreciated.

Thanks in advance,

Sid
