Does the Optimus Slider have the same internal memory as the regular Optimus? I currently have the optimus and the lack of internal memory is getting annoying. Does the Optimus slider have a better internal memory? Better as in that I won't have to be dealing with the the "low space storage" notification. I'm also thinking about rooting my current optimus, but if that fails somehow that getting a slider would be my back up plan if the internal memory is good. Thank you!
