I got a Kingston16GB microSDHC Class 10 2A from eBay back in June and it was doing great. Then, all of a sudden, this morning, I got a "Removing SD Card" notification as I was booting up. My eStrong file explorer didn't see it in the phone and it didn't show up when I connected to my PC via USB. I then tried it in my PCs smart card slot and nothing. Meanwhile my original SanDisk 2GB seems to work fine and Kingston is sending me a new card upon receipt of my dead one. My question is: Not having backed up my Kingston - Should I expect any problems running the phone with the SanDisk until I receive my replacement Kingston? I'm not worried about my music, pics or docs cuz I can replace them from my PC - but I've installed & uninstalled a number of apps since I switched cards (and I see that the SD card has folders for a lot of the apps). Is there anything else to look out for? My dInc does seem to be a little jerky (like on installing updates0 - but otherwise I haven't noticed any probs. Any advice would be appreciated. I'm still running 2.1 update 1 - no root. Thanx!
