Firstly, regarding my other thread about Chinese 'clonephones', I took the excellent advice eventually of 'Ancient Observer' and purchased a Samsung Galaxy Apollo and am mighty impressed with my move into the 21st Century/smartphones/the Apollo.
For XV, if it is similar to yours, setting up emails is not too difficult and if you wish to PM I may be able to help. The phone should do it all for you without a 'third party' app, although no doubt evnetually you may decide you wish more options than the Samsung 'built-in'.
Downloading apps (many unbelievably free!) straight to the phone is likewise a doddle and I will offer help if you need.
