I sent my iPhone 5 out for modification awhile back and used my iP4 during the duration. Fast forward a couple of weeks and with my iP5 returned was happy to pop my SIM back into it and go about my business. Sure, it is sleeker/faster/brighter/whatever but in all honesty- I missed the iP4 jailbroken to such a remarkable degree, went back a couple of days later and placed the SIM back in. I have my iP4 set up perfectly, for me. I ran iCleaner Pro and it runs like a charm. I have %Hook installed so the feel is faster (even more so than the 5). My theme suits me just fine and little additions like "Fast Photo" and other tweaks that customize the full experience of using my iPhone make using it a joy, even over that of the iPhone5! Anyone else simply shrug at the suggestion that although the iP5 is sure enough a 'better iPhone' the simple joy of using a jailbroken 4 is sublime?
