Hack Fixes MMS on Unlocked Samsung WP7 Handsets
One of the odder quirks of Windows Phone 7 to appear since the platform’s launch has been the absence of Automatic Data Configuration for users who swap SIM chips and network-hop with their unlocked handsets. The capability most affected by ADC being disabled seems to be the ability to use MMS messages. While HTC and LG users have been able to get by with work-arounds, there wasn’t much owners of a Samsung WP7 device could do. Now a hacked app has been released that will restore MMS functionality to affected Samsung models.
ADC should let the phone communicate with the network it’s connected to in order to retrieve all the settings it needs in order to use the network’s services. Samsung defended disabling ADC by saying that its phones are intended to only be used with a specific carrier; while it’s fine to encourage carrier loyalty with subsidies and contracts, users who buy unlocked WP7 handsets, fully capable of working on an assortment of networks, shouldn’t be unnecessarily limited in software.
The new fix for Samsung WP7 models with MMS woes uses Samsung’s own Network Profile app, but with a few modifications to enable the full functionality you’ll need to setup the correct MMS server. Since the modifications mean this is no longer an approved app, you’ll need a phone with the Chevron jailbreak in order to launch it. According to an unverified tipster, Samsung itself may offer proper network reconfiguration in a future software release.
