Hi. I am a low end user of cell phones, but would like to get a new phone that will let me do WiFi as well as pre-paid calls. Is the LG Optimus T the right phone for that? I'm told that the APPS on it won't work without a data plan, but why not? The Apps all work on an iPod or iPad without a data plan, simply through WiFi. Would appreciate any advice here. I don't want to spring for $544 for the new Nexus S of course. Arroway
