I have a 2gig Micro SD card in the Pearl and it can all be used, the BB features states up to a 1gig card. Is anyone using a 4gig card? I figured maybe a 1gig card was maybe the largest available when the Pearl first came out.
Also, what is the hole on the right side at the bottom of the Pearl?
Odd how no one answered the 2nd question you asked. That hole on the bottom of the pearl is where the microphone is. Unless you're talking about the hole on the bottom of the right side of the pearl, the hole which goes through the pearl's casing. THAT hole is for attaching things, usually wrist straps or a lanyard for a necklace.
