The iPhone Dev Team has explored the SMS feature on jailbroken iPad 3G which is one of the most demanding and exciting feature of this iPhone OS based jailbroken device. They already have jailbroken iPad through Spirit jailbreak tool which will be available to users soon.
The iPad is using a T-Mobile SIM cut down to the size of a microSIM and sending message through its baseband (no GUI). This requires a SIM with SMS Plan.
Following is the video demonstration where Musclenerd, iPhone Dev team member is sending SMS messages from iPad to the iPad Baseband without GUI.
Anyhow, the iPhone Dev Team is working hard to bring iPad jailbreak tool to meet the users expectations level by exploring the hidden features of this device and hopefully they will also get their hand-over to make calls from jailbroken iPad 3G, which is an other demand from iPad jailbreak.
So, stay tuned to know further about iPad 3G jailbreak by iPhone Dev Team and they can release iPad 3G jailbreak tool Spirit any time from now.
