i recently bought the blackberry 9630 tour from sprint the other day and i was going through the mobile network settings option and i saw several different choices. what should it be set at? i saw GSM/UMTS, 1XEV and Global. it was set on global. i've been reading other post and people say to change it to 1XEV to save battery life. should it stay set on that? i don't think i'll be going out of the US anytime soon. thanks for your help. oh yeah, is there an option to have threaded text messaging for the tour? my gf just got the new old from T Mobile and it is has and its awesome. thanks again for your help
