Cell phone carriers data and voice

<p>Hi again - reactivating this thread - as i get closer to making a decision. It sounds like I will be fine with either Verizon or T-Mobile (my 2 choices). Does anyone have an APP to actually report data speed? That would be most appreciated.</p>

<p>Also - are there Pitt specific or other useful Apps that only work on apple IOS. I am wondering if it is worth going with an iPhone or if an Android would be adequate? Any opinions of Android vs. IOS would be appreciated.</p>

<p>Thanks!</p>
