as far as i know if your phone hasnt received an update thats pretty much it for your phone. I have a focus and it was on 7720 and if i didnt use 78er tool i would be stuck there for ever.
Well, I went ahead and did it and it worked like a charm. No problems at all. I love that I can resize tiles now. I have also noticed that my battery life has improved significantly, not sure what that's all about, but hey I'll take it.
