few things ...

hey there
added a few things for your consideration

1. changed build settings
-build active architecture only
-- debug:No (changed from Yes)
-- release:Yes
… so that in the debug environment it builds for both simulator and device

2. changed the NSURLConnection in Balanced>tokenizeCard to happen inside an NSOperationQueue block with separate blocks for success and error
3. added some keys for the tokenize NSDictionary response (obviously incomplete, but works for my project's purposes)
4. added a semaphore in OCUnit tests in BalancedTests for testing of methods with asynchronous calls

there's a bit to be done, for example required params when you use testTokenizeCardWithOptionalFields (like street_address, which is required)
