I am back again (please see my other testimonials below). I bought two Sony Ericsson K610i phones on eBay, both were locked and branded to T-Mobile. I tried unlocking and debranding one of them myself, but unfortunately I was unsuccessful in doing so. On 30th November 2009, I sent both phones to Fone Fun Shop to be unlocked and debranded. I received them back on 2nd December, both done and working as normal. Gone is the T-Mobile branding and now both phones can be used to their full potential. Fone Fun Shop offered me an outstanding service and I would give them 10 out of 10 yet again. Keep up the excellent work. Thanks a million!!
