Sorry if off topic. I don't know where to turn.
There is no big difference between LG Scoop and LG Rumor. Both are mobile phones from LG and they are exactly the same. However, one of the little differences between the two mobiles is that the distribution of the two mobile phones is done by two different telecommunication companies.
The distribution of LG Scoop is done by Alltel while the distribution of LG Rumor is done by Sprint. Another difference is that both come in different colors. Although, both LG Rumor and LG Scoop use the same camera, but LG Scoop has more options and settings that cannot be found in LG Rumor.
Aside these little differences, both mobile phones are the same, most especially when you check certain features that come with the two phones. The type of keyboard used by the two mobile phones is the same. However, the decision to buy any of the two depends on one's choice.
I had an LG Scoop that's a good phone I like. My wife needed a new smartphone, I wanted to buy one like mine, but I didn't have one. I read it here http://lg.manymanuals.com/mobile-phones/rumor-lg260 about LG RUMOR LG260 MANUALS and realized that it is no worse. Bought without hesitation everything works fine.
