So I'm totally confused now, does your modem send a HUP on the PPP tty
when NO CARRIER due to context deactivation or not?  If it does, then
you still need to detect disconnects and re-create the context.

netreg and ussd are not really meant to be created in post_sim stage.
They should be created in post_online.

radio_settings, sms, phonebook, gprs and gprs contexts are fine here.

[PATCH 1/2] linktop: reimplemented linktop plugin with minimum features.

[Amit Mendapara]

[-- Attachment #1: Type: text/plain, Size: 11264 bytes --]

The device supports subset of ST-Ericsson AT command extensions but nither
STE nor the MBM plugin works with these devices.

- Supports voice call and has builtin soundcard but unable to hear any sound.
- Supports sim toolkit commands but I am unable to test this feature.

Fixes MeeGo bug #14784
