I bought LG G3 few days ago after my iPhone 4S lock button finally broke. I thought about iPhone 6 plus for it's larger battery. Unlocked GSM version is over $900 on Amazon. LG G3 unlock GSM is around $450... I hate 2-year contract thingy, using this $450 + $50 accessories + $1,200 Straight Talk 2 year no contract = $1,700 In comparison to Verizon 2-year contract $400 iPhone 6 plus + $1,920 2-year = $2,320 with god knows hidden fees and receipt of my soul... I think I made the right decision...
