Hi, got a new iPhone today. Was wondering if you knew anything to help me out.

It came unlocked, so I just plopped my t-mobile SIM card in and it worked, I could make and receive calls, but now I'm just trying to get data to work on it. I got the tzones internet on it for 9.99 for 100mb or something like that, and w/ extra usage it can run up to 15, so essentially 15 dollars for unlimited data. I got the APN configured, so I'm just waiting now. So my Q's are:

1) I have Cydia on it, what do I do with this?

2) I plug my iPhone into iTunes and in the summary I see software 2.1. Should I upgrade (and still keep the unlocked status on)?
