Using Jolla C as main phone this week and I'm overall satisfied, serves me well, updated to unreleased 2.0.3.11 and have no issues (at least not known to me

• Wired headsets -- have bunch of Nokia branded for 1 ear, unfortunatelly they semi-work as Jolla connector is not OMTP, so I switched completely to Plantronics BT M55 headset. BT consumption is minimal and can be safely left "on" whole time (which is not the case with [at least] my N9).
  
• Lack of compass -- not so bad as I initially thought as it seems I don't use it at all (have Garmin for car navigation and I don't use phone for navigation).
  
• I find GPS pretty fast and *accurate* (ticked everything under "custom/advanced settings"). To be honest, power consumption with this settings as also quite low.
  
• Much improved readability under sun compared to Jolla 1. It can't match N9 tho ...
  
• Transfer of contacts from Jolla 1 via BT Sync -- semi successfull, most transferred, some not. Anyone know solution similar to N9 export of all contacts into 1 huge VCF file? That's working great.
  
• 4G -- I was too fast writing somewhere on TMO that's working for me. Not quite true, depends of location. At work is always 4G, at home almost never. Most of the time 2G, sometimes 3G and if the constellation is right, even 4G for few minutes ...
  
• Size and feeling in hands -- great, no complaints (size wise I prefer form of N9, but I "adapted" to 5" devices and Jolla C feels great). No complaint regarding power switch, I actually prefer this location.
  
• I absolutelly love red tint of back cover, it just shines in the hands(s), big plus for this.

Mapbagrap (https://www.mapbagrag.com) updated their flip and cover cases selection to include Jolla C variants. I'll wait if Jolla came with customized version, if not, I'll probably create my own
