Nokia :: 5800 XM Music General Error

This is getting really frustrating.I bought this blue nokia 5800 XM in January (Australia), and in the past month its been giving me trouble.Okay, right now: Running v50.xx..My phone is having a 'general error' when I try and play music in the music player.Only when I find songs via the file manager I can play them..One at a time.This is the second time within a week that its done this!The first time I googled around and found I had to 'hard-reset' then clear my memory card of bad sectors.Done that, it fixed..Until now.This isn't the only problem, at the start of the month my stupid phone would restart itself just for fun, and the alarm doesn't function properly (when I touch/slide to 'snooze' or 'stop' it doesn't respond until a minute later) And the memory card has wiped itself before aswell

I reformatted the entire phone and memory, clean install of firmware and everything but still I get problems? Why? Think I'll go back to my old SE w910i it was much better..No problems with it ever (even after I dropped the battery in water).BTW I think I should have 1yr nokia warranty (does it cover first year from purchase?), but then again all they'll tell me to do is wait my time every week re-formatting the phone.
