APN settings app is broken.
1. It's possible to add APN but not to modify or delete. Long-press on the apn does not do anything.
2. Restore to default hangs, then entire app becomes blocked by rotating progress thing. Unable to terminate.

actually not a big problem - data works fine, settings may be wiped using sqlite3 tool (com.google.telephony.provider/databases/telephony.db)
EDIT: I assume the error is when you manually add APN (settings > wireless and network > mobile network > Access Point Names > menu then "Add APN"), after you created, you can't edit, even tap spamming does not work...
