* Add note about getting GadgetBridge from F-Droid
Hopefully this is useful and will save folks some frustration
* Add note that GadgetBridge should be downloaded via F-Droid
There's an "unofficial" version on the Play Store that is outdated and doesn't have PineTime support
* Fix typo
* Add starting version, reword a bit
Initial support version is a little fuzzy, 0.47 states it's "not yet usable" but changelog doesn't specify when we've crossed the "usable" threshold.
