Ask questions, answer question (make friends here on xda). For the antenna thing, on most devices the antenna is not to be messed with as manufacturers already have it in the ideal location and configuration. Like in the HTC rezound all the antennas are in the back cover.
Hope I helped

While some devices have an antenna jack for factory test, it is often inadvisable for users to use this antenna.
If you are looking into signal strength improvement, it is strongly recommended to use a close-proximity coupled antenna combined with an amplifier - look at Wilson Electronics' cradle+amp solutions as an example.
While it might be possible to add an antenna jack to many devices that replaces the built-in antenna - don't try this unless you have a spare sacrificial device or two, as such a modification will be irreversible!
