I am wondering if you've seen the official FAQ for the 8100
Which for "SD Card Failure"
says clear as day:
You receive the following error when using a 2 GB microSD memory card with a BlackBerry Pearl 8100 smartphone:
SDCard block length is unsupported.
The BlackBerry Pearl 8100 smartphone supports memory cards with up to 1GB storage capacity.
This is a previously reported issue that has been escalated internally to our development team. No resolution time frame is currently available
There are two obvious things here:
- T-Mobile's marketing dept was incorrect in printing the 2 gig capability
- It's not going to work
Good luck anyways.....
