US Newbie Questions - Esato archive

Posted by krdu
I am about to buy a 750I from a US seller. It is used, "unlocked," and "set up for T-Mobile." I am sure that it does not have the latest firmware which I assume is RN035. My area has Cingular 1900MhZ service.

1. Will it work on Cingular?

2. Why not?

3. Do I need to unbrand it? If so, how?

4. How do I install the latest firmeare?

5. I went to SEUS and under country "US" I could find the W800 but not the K750, K750I, or D750. But the UK site did have the K750I. Why? Can I use the UK files in the US? How?

I am sorry if I am asking questions answered elsewhere. I have been looking around for two days and found the answers to many questions but not these.
