I'm on orange and all of today I've not been able to get a signal on my blackberry 8520 curve, nor can I search for networks manually on it. I've got a backup cheap samsung phone which gets a full signal and can send texts and make calls yet the blackberry can do neither with the same sim card in. Its leading me to think that the antenna is dead but is there anything I can actually do in regards to this? I can't find anything of help on the orange website in regards to faulty handsets or what I need to do to get it fixed and sorted out. Its less than a year old so I'm guessing its applicable to a 1 year manufacturers warranty?
