Repo name changed to: https://github.com/nosebleed/jpeg-ttl-cam
Chunk size is increased to 128 making the writing on the microSD much faster.
Here is a public repository with the arduino compatible sources which work with this camera. I use it with success with a 7.3Mhz crystal for the AVR, with 3.3v input voltage and with 115200 baud rate.
Any comments / fixes are welcome :)

And sockets for crystals !
Plz bring 7.3mhz crystals :)

A replacement GSM shield for SMB5100 at 19$:
Finally! A promising shield for this module.
Contains all electrical components needed for SIM and has the SMA connector in a drilled position on the board. Awesome !!
Eventually the “SIM removed / SIM inserted” was caused by some kind of interference between the antenna and the electronics.
I always had the antenna lie above the sim card. Accidentally I placed the antenna on another spot and everything worked. I run the scenario multiple times to ensure that that’s the problem. It is.
SM5100B works great even with SPX outputting 4v.

Unfortunately, the above is not a solution. I’m still getting “SIM card removed"
Sleahey said something about missing components on the shield.
"In the SM5100B, P.14, up the top there are three notes.
1)SIM_VCC need add three capacitor: 4.7uF,0.1uF, 27pF.
2)SIM_RST,SIM_DATA,SIM_CLK lines also need add 27pF ca
3)SIM_DATA need to Pull-up with 2K resistor to SIM_VCC."
Can someone from tech support look at this matter?
While the TimingAdvance value is the key to GSM triangulation the SM5100B gsm module always returns 0.
For my case the “SIM card inserted/SIM card removed” issue was because the card was full of saved messages. Deleting all messages immediately fixed this problem.
No public wish lists :(
