Continue on with the "app removal" thread over at xda... pay particular attention to how the phone acts after you remove nfl and nascar sprint apps.. i've noticed the phone not only responds faster, but it loads other programs faster, reboots faster... and those are the only 2 apps i chose to remove so far... i think the sprint bloatware holds back every phone its thrown on.. so give it a try and post your results... for those that do not know what thread im talking about, try this link...
