As I wrote... It seems the GPS function works fine when called from the phone itself, but not when called from iCloud. I believe many people don't seem to care about this ability.
So instead of properly hacking the normal baseband in the iPhone, developers of the unlocking process went the dirty way and grafted a more easily-hacked iPad baseband in the iPhone? On the other hand... The iPad does have a GPS itself, so why wouldn't it operate the iPhone GPS properly?
I have believed and still believe that jailbreaking is a really dirty way to get things done, full of incompatible, unfilter-able, unstable or downright dangerous (for the life of your phone) software. This half-baked graft of an unlock proves my point once again.
My first concern was the calendar issue. After about 3 hours of call with Apple Level 2 service in California with incredible background noise as the tech told me she could hear, I finally managed, with her help, to maintain iCloud, iPad, MacBook and iPhone calendars in sync, on wifi, after creating a new AppleID for iCloud purposes, as she suspected a data corruption from having so many different devices trying to communicate with iCloud. I still don't know why whe didn't came up with that circumvention during the first, hours-long calls I had with Apple previously. I imagine what it would have been like for the tech to stay on the phone for hours with a customer with a foreign accent over powerful background noise and receiving screenshots in two languages not known.
As I tried other functions, I noticed Find My iPhone didn't actually find it, and reported it as having no connection, to which the tech advised me to restore software, wich obviously can't be done since I would lose unlock and still don't have what it takes to unlock again and since clear instructions are so hard to come by. As soon as I moved out of the coffee shop and added an event I just got by email as I was walking, back at home this even wasn't added.
Now, my main concern is the fluctuating cellular and wifi signal. I don't know if the calendar problem has any link with the former, but constantly losing connectivity surely doesn't help keeping the calendars in sync, and is a possible cause for draining the battery really fast. Without moving the phone, it can be anywhere from 5 bars to 2, to losing service. Is that a baseband issue as well?
Edit for Baggio: SwiftUnlock never answered my request about the exact process. Site appears as I presented previously in Safari and Firefox, plus, they are not answering their email. I can't rely on vapor, can I?
I have a hard time understanding how IMEI, database-based unlocks wouldn't have been available as it only depends on the providers.
