SGS2 + CM9: MMS Battery Drain

Noticed that the "Messaging" app appearing in the Battery Usage screen. Then found out that it's due to an incoming MMS. See screen shots below.

Tried deleting both APNs for MMS (2G & 3G), but didn't work. The drain starts as soon as the MMS comes in.

 Restored the MMS related APNs (since removing them doesn't solve the battery drain)
