Description of Problem:

Added a webservice call to the MonoTouchCell's sample which loads approximately
1000 records into the TableView.  When randomly scrolling and clicking into the
DetailView of a record the application will crash.  This happens in both the
simulator and device.

Steps to reproduce the problem:
1. Load application
2. Scroll down table
3. Click into record exposing DetailView then return to table
4. Repeat step 2 until crash.

Actual Results:

Application crashes.

Expected Results:

Application doesn't crash.

How often does this happen?
