Almost perfect Got my SMSes back but the SMS app seems to list them in random order, the top one is someone I've not spoke to for ages, but when I click into someone everything is correct. When new SMSes arrive they are put at the top, in the correct order. so hopefully it will sort itself out.
OK, but... I tested several b/u apps and this is the only one I found to b/u & restore SMS/MMS group conversations, but some of the convos and some MMS got lost or misplaced when restored. Restore was quite slow, but that's okay (2000+ entries). Had to transfer to new phone. Only saves to internal memory (SDcard0). Used file manager to move file. If you could fix to save to external SDcard1 would be nice as well. BTW, file is too large for attachment to gmail. Don't get me wrong, I like it. Will gladly give 5 stars+
