I have had problems with my GPS not getting a fix , and between updates and jailbreaks, sometimes it works PERFECT, and other times not so much. So after 3.1.4, I ran it a while, and all GPS related apps worked perfectly. Next, I jailbrake and installed cydia, again, GPS perfect. Yesterday, I installed SBsettings, and now I have less the stellar GPS performance. One problem I have always had when installing SB, is that after installing through Cydia, I get the wheel spinning, it never stops, and I have to reboot manually. SB settings works perfect, but not my GPS. Any help appreciated!
