Hi all.
This isn't strictly Bitpim related (yet), but I'm attempting to reverse
engineer the format of the Sprint Rumor's contentInfo/executionInfo
databases. It's going very well for the most part and I have 90% of the file
figured out, but one thing I can't figure out is their string storage
techniques.
Perhaps someone in bitpim development will recognize the format, or have some
insight?
First there's a type code
0x00 0x04
Then a field num (incremented for each variable in the record)
0x36
The a field length
0x10
A marker of some sort
0x00 0xFF 0x00
The string, in ASCII (null terminated)
Applications
After the null terminator, though there's what is apparently garbage. The
string length includes the marker, terminator and the garbage, so it can be
used to jump over accurately. Sometimes it's got some random bytes in it.
Sometimes it's all zeroes. Sometimes there is no garbage.
It's not a hash of any sort, because it's changes between two identical
strings ("Applications" appears alot), and even the number of bytes of
garbage changes between identical strings.
It also can't be some sort of padding, as far as I can tell, it adds all
sorts of number of bytes, and the strings don't start or end on any special
address.
Also, the string 0x98 0xFE 0xCD 0xAB shows up a lot in the garbage as well,
but not always and not always at the beginning or the end when it does.
Anyone seen anything like this before? I've been manipulating the files with
a Python script, and two files one before I added a ringer via the internet
and one after and the *only* difference between the file I generate and the
reference file is the lengths of the strings/record/file and the lack of
garbage. Yet the reference file works and mine doesn't, so their must be
something to it...
Thanks for your help.

The format of the contentInfo file might be similar to what is used on the LG PM225 or PM325, both Sprint phones. You might look at the code and protocol definitions for these phones. How do you connect your phone? With a data cable? Bluetooth? What drivers do you use? I ask because while there are 3 Rumors in my house, I can't borrow them very often, so don't want to waste time trying to figure out how to connect.

I don't use any drivers -- run Linux and it pops up as "Other CDMA phone". Filesystem access works like a charm, of course. -- Jack |

There's a data cable for it http://www.buy.com/retail/product.asp?sku=206616217&listingid=25137829&dcaid =17902 , I sent a nearly complete (worked for me but otherwise untested) auto-detection and contacts integration a month ago to the list, that just needed the specification for what ringtone and if it's a cell/mobile/fax done.

Thanks for the pointer to the cable. I just ordered one. I'll try out your code when the cable comes and check it in for others to try.

Has there been any new progress made on this phone? I'd like to be able to obtain the SMS, call history and PhoneBook if possible. I just tried one yesterday in 1.0.6 (WinXP) and noted the following information. When run as Other CDMA, it will download the file system. However, the back up entire tree will not function from the root folder. Each node below the root will back up using the backup entire tree selection, when each node is selected individually. I tried running it in each of the LG selections with both COM port variations. Each failed although a couple appeared to be working prior to failure.
