I have a rooted HTC Desire running Ginger Villian 2.1 with the 126.96.36.199-defrost-bravo+ kernel I'm self employed and I've recently been told that sometimes when people ring my mobile (t-mobile UK with Orange roaming enabled) that they get a "this number has not been recognised" message,, I have also experienced this myself so it's not like people are my number wrong.. I understand that I will not always be within my network coverage and that should forward my calls to my voice mail when that happens. I have phoned up business customer services who have reset my voicemail and I've also removed battery with power on to reset my phone, they also said that they might change my sim card and phone if it carries on,,,,, but to me it sounds like it could be a network fault and nothing to do with my phone and when I pressed this issue they said that it could be that the network can't cope with any more calls and i guess is just dumping calls. Now just in case they want to replace my phone (free next day couriered replacement under warranty) I need to make sure that I have everything in place to get it back to stock:O Hopefully I backed it up before I put another rom on it (had froyo before) and I do have a goldcard,,, what else could I need?? Does anyone have any idea what could be causing this?
