What is the maximum size of micro SD card can I use for my sidekick slide? I ordered a 4G micro SD because I read on this site that it can support up to 4Gs. However, I just noticed on my user manual and TMoblie's Sidekick website that the slide can only support up to 2Gs. In addition, the they are on selling up to 2Gs in their accessories section (Tmoblie Sidekick website). So is it up to 2Gs or 4Gs??? I already spent it on the 4G...which I hope I can return online.
