How do I migrate my SMS (text messages) from iPhone to Android?
After some digging into google, I came across a software called Backuptrans. The features listed include Transfer SMS between Android and iPhone, Save SMS from Android/iPhone onto local database on computer, Restore SMS from local database to Android/iPhone and many more.

I do not have an iPhone to check this software. This seems pretty good. The work steps are as simple as importing from iPhone to the computer and exporting to the Android device. More details with screenshots can be found here

The only downer for this solution is that you have to pay some cash (a minimum of $29.95) to use it fully. Since you are not comfortable with iSMS2droid (iPhone SMS Import), this seems to be the best option available. 

On an additional note, iSMS2droid is worth trying before you buy Backuptrans.
