Sheik,
I tried to solve my problems on my own and don't bother you with a lot of questions but it didn't went very well and I am back here with more questions, sorry
I almost like everything about CM7 but there are some issues, I installed the stable version but there are a lot of errors when I connect to internet. first of all every time I open the browser it gives me an error which keeps coming but it seems it wont cause any problem. The more important issue is that, market is not working. I flashed the right Gapps and everything works except the market. It starts but wont download anything. I cleared its cache but nothing changed. I tried to update it with new market but after update it didn't even open anymore, force closed all the time ! So I wiped the ROM, flashed the ROM and gapps again, this time I checked it before restore the system data from TB to see if that's what conflicting with the app. It was the same and it didn't solve anything.
So I'm thinking about other ROMs, what do you think ? what are the best ROMs there? I like rich featured ROMs. Do you know any good one ? I was thinking about MIUI but it's kinda similiar to iOS and I don't want it to be
