I will try to code a demo which does side scrolling tonight, but I don't know opengl, so I won't use it.
My phone is getting worse every day (I haven't used it as phone as a matter of fact for a while) but in case it does manage to show smooth scrolling, in the 5 seconds idle period, when it's not attempting to send an MMS to the GOD DAMN myFaves service (and thus trigger GC), I'll post the code.
