If I jailbreak my iphone 4s will it become laggy and glitchy?
i only plan to put a couple tweeks and maybe a theme
According to Apple developers, your iPhone will become laggy and glitchy after you jailbreak it. This is because jailbreaking is considered a hack and there are unexpected things, which would happen because of that.
No it wont, If you're getting a theme I would recommend "ayecon"Some good tweaks would be dasboard x, stride, animate all, password pilot
