Text issue: SMS messages showing as MMS

[gaveup]

Currently using Handcent (on my ATT GS2) as my messaging app (but have also verified this in the stock messaging app). Whenever I get longer type of texts from my friends (most using iphones) it shows as a MMS message.

Is there a setting I may have missed to stop this? It's getting really annoying.

Also, is there a way to disable that stupid slideshow when someone sends more than 1 picture in a text?

Your first question: there is nothing you can do about. Some phones split long texts and sends as separate SMS but some instead send the long text as an mms so it doesn't get split. Nothing you can do about it on you end.
