I recently "brought" Phone tools, but my phone seems to be slower because of it (no I haven;t put anything on the phone yet, it has space), it's like lagging and also while it does connect to my computer I can''t get my phone book on it, it says "reading mobile phone's contacts failed" why does it do this, it had no problems yesterday. please help.

uninstall phone tools and restart you'r systeminsert you'r phone tools cd and installed that again before install finish connect you'r mobile to you'r computer.(you must reset mobile after uninstall phone tools.after that you can sure ther problem is finish.
