Thanks Morfiy, I have noticed that it is a little laggy with the Int2Ext method, but I was just happy to have such a great version of Jelly Bean and all my apps running on this old tablet! I'll give your instructions a go as soon as I can get a chance.
Thanks PBP - love this ROM, only problem is I'm constantly stuck with "insufficient memory" for installing apps. I've tried Mounts2SD and Link2SD, but both end up running out of room fairly quickly. Anyone found a better solution?
