Hmmm, well it seems I have the issue too. Tried clearing Data etc inside the Google Play Settings in system settings. Im running Omega ROM on my SGS2. Can anyone help me without me having to reflash? >.>
this happened on my indulge allt he time. Try connecting to Wifi while in airplane mode. That worked every time for me. I really don't think it's an lg motion problem. I think it's a Metro PCS issue. Try turning off the ability from downloading from unknown sources too. That might help too if the airplane mode doesn't.
Same issue for me, can d/l over wifi, but not 3G. Have tried all the fixes I can from searching google.
Galaxy S2 Vodafail (AU). Rooted. ROM, I9100XXLPQ_I9100OXALPQ_XEO.
I had the same problem too, turned out to be just a memory issue. So I deleted a load of apps I didn't use and transferred a few to my SD card and now its fine
