yes its the desire, not the s or x or anything and the S3 was insured so its getting fixed.
Totally got root access, pretty sure I've got the recovery thing sorted, not sure if I've done the nand backup thing properly though (maybe titanium backup does the same thing??). Bit of a panic earlier when I got that loop thing on boot going, but all sorted now. Great threads on here for donks like me that dont know what they're doing... that 'all things root guide' is the business for anyone wanting help.
Tommorrow I'll flash a custom rom, do the a2sd thing, then look into putting an o2 sim in the orange branded phone - that was the whole point anyway. Too late to try tonight...
