This app is not free and you will have to pay $19.99 but the benefits that you get are great. Once you download PhoneIt-iPad you can activate it online by entering your iPad�s serial number. There is only one device per purchase so once you have entered your serial number you won�t be able to change it. This hack only works on the original iPad with 3G so if you have an iPad 2 or one with WiFi only capabilities it won�t work for you.
Another thing to note is that a plain data SIM won�t work either and you will need to get your hands on an activated SIM card with mobile service. If you have a SIM card in a phone and you make calls on it you can use this on your iPad to make calls. The last thing to point out is that in order for this hack to work you need to have a jailbroken iPad because this hack requires access to the Cydia Store.
You can use Redsn0w to jailbreak your device and there are plenty of instructions available as to how to do this. The developers behind this hack are hoping to have a version available for the iPad 2 very soon but right now there is no support for the iPad 2 and PhoneIt-iPad will only work on the iPad 1. PhoneIt-iPad can be found in the Cydia app store so if you like the idea of making calls from your iPad this could be the thing for you.
