My 4GB card is maxing out in my BOLD. when I switched from my 8900 curve, I seemed to have lost a lot of space, so am going to get a 16GB, are there any tricks or pitfalls to watch for when putting in new cards? when I switched to Blackberry, my old card from my other phone, all of a sudden had to be formatted, and lost a bunch of stuff. is there a method to putting in a new card and moving the old data, music and pics to the new card without causing re-formatting issues? when that happens ,all is lost!
