Broken Cellphone Charger

Whaaa…!!! My cell’s charger is broken! Don’t know why, just suddenly won’t charge. Well, it’s definitely not the cellphone ’cause I’ve tried charge using my PC and it works (I’m charging it while typing). Check to Nokia website, it’s apparently that the charger’s warranty is only 6 month. I’ve bought this set at May 14th, 2010, been 7 months 6 days… ugh…
Now what, 3 choices: act dumb and keep going to Nokia Care, buy another charger, or keep charging from PC… doh…
