agreed. Handcent is what u'd be after if ur looking for an iphone-ish sms app.
That being said, it still doesnt hold a candle to the responsiveness of the stock sms app, even with the overclock.
I do however love the bells and whistles of handcent (mainly the popup box on incoming sms msgs.).
I totally agree with you Spz0, I've been using Handcent sms now since 2 days after i got my phone, the only other app I had used was GoSms which has alot of the same features as handcent, but I stuck the handcent just the same. I do have some issues sometimes though, like after deleting a message I'll end up receiving it again. I've been trying to figure that one out since day 1. However, I love that app either way.
