Hello, i have a 3g 4.2.1 baseband 6.15 but he is very slow. when i do the jailbeak I disable multitasking etc.

Is possible to downgrade the version to get him faster?

Hi, i downgrade to 3.1.3 is a litle fastar but not 100%. i think is because i have 6.15 baseband. is possible to put the normal baseband again?

if your iphone is on 5.8 bootloader, you can restore your normal baseband again..
