Using on T-Mobile USA 3G

[michael2041]

Hi, I was wondering if I bought an unlocked LG Eve and updated to Froyo, would it work on T-Mobile USA 3G or 3.5G? And, would there be any differences if I used it on T-Mobile USA? What about difficulties updating?
Thanks

One more question, could I use it with the $10 internet plan?
