I currently have a 3gs i bought in late 2009. I was planning on getting the 4s but i felt like i could get another year out of my phone and save money. My 3gs has felt pretty sluggish from the past year and the battery is horrible now. Also, i havent downloaded any apps in the past 6 months because of the slow performance and harsh battery drain. What i want to know is if there is a big jump from the 3gs to the 5. Im kinda bored of ios right now but my friend says the speed difference is worth it. did anyone here go from a 3gs to a 5?
