No i toughed i found a normal size 2900 mha battery but it was a fake one. I do have a 3500 mAh battery which comes with an extra big battery cover because it is thicker than the stock battery, and i am very happy with it! I dont always use it, but it is very useful sometimes, like when going to a festival for a weekend, or when you are on vacation and need to travel a long time.
Also, now my stock battery is almost dead, and i ordered a new 2350 mAh battery which is as big as the stock battery (so no need for thicker battery cover). In three weeks he will arrive and i can tell if it works good.
Btw. I always order these stuff on dealextreme.com. its really cheap and it is really reliable/safe. Only downside is that it has very long delivery time (depends on where you live, mostly around two weeks or more).
