Hi, I've purchased a new S2 on the T-Mobile UK network. Looking to upgrade to 2.3.4. but cannot get my head round it all. The phone is not locked (tested with other sims) and has no T-Mobile branding, is this right? My CSC is XEUKD1, what exactly is this? I've read that XEU is for UK but what is the KD1 part? Should I not have a CSC specific to T-Mobile? PDA i9100XWKF3 Phone i9100XXKE7 what do these numbers mean? which one will update to KG3? I've tried reading several hundred posts but this is all so confusing. Ex iPhone so go easy!!!
