please can someone help me. I have a htc desire and am just a novice at using one. when I log on to facebook it allows me in but when I try to download my notifications I have a message which reads 'an error has occured while fetching data 'null'. I have only been using this phone for a month and it's very frustrating. I have tried deleting the cache, removing and replacing battery but fault still persists. This could be a problem with facebook I suppose but all other aspects of it works. Other than this problem I think the phone is brilliant.
