Yes, that's true now. (RS-)MMC uses 7 pins and only 1 for data transfer. This is really old and outdated standard. SD uses 9 pins and 4 for data transfer. Newer MMCmobile, backward compatible with rs-mmc uses 13 pins and 8 for data transfer. Problem is that current USB readers on market can handle only MMC and SD protocol. MMCmobile in current reader uses maybe 4 but most probably only 1 pin. I have two USB readers (both cheap in ~5$ range) and one does 1.5MB/s for all mmc and my newer 2GB kingston mmcmobile, second one does 1.5MB for mmc but 3.8MB/s for mmcmobile both for reading and writing. I have ordered
(supposedly) next generation reader (also cheap) with all 13 mmcplus pins
http://www.sharkoon.com/enghtml/usb.htm#xcplus that could read even newer mmcmobile cards faster.


As for others, your ignorance does not mean the format is not used ;-) At least here in Europe MMC cards are not rare at all.

MMC derived formats are a bit older than SD and are specified by MMC association http://www.mmca.org/home (nothing realated to Nokia) Current MMC 4.1 format is better than SD and the standard is open. There is no reason this format will die in any near future.

SD cards are specified by http://www.sdcard.org/ and standard is not available unless you sign NDA and pay. That's why some linux devices didn't suport SD because the protocol was not known and there were no open source drivers for SD. Now I think something was reverse-engineered and some bits were found in various specs by manufacturers so most parts of the protocol is known. Also I think recently SD association released some stripped down specs (excluding SDMI content protection).

Yes I heard similar thing. They took already existing parts already sitting on their shelves which they used for phones at that time.
Well that's probably afterthought and not the main reason. You can use bluetooth for that and browse pictures directly from N770 without removing card from phone.
As for normal cameras If you use SD card then obviously not. If you use MMC/MMCplus/RS-MMC/MMCmobile in camera then yes. Also in IT2006 big MMC cards are readable without closing the door.

As for the RS-MMC slot, this was one thing I hate too. I was thinking quite hard before geting N770 due to this slot. But replacing it with microSD as you suggest is not much better.

BTW I have just read the Specification 4.x Application Notes PDF and it seem even for 1 bit transfer there could be speedup when chaging 20Mhz bus speed to 52Mhz which should give 260%. 1.5MB/s*2.6=3.9MB/s which is what I noticed in one of my USB readers. And this is over 1 wire so if OMAP 1710 chip inside 770 can switch MMC bus speed from 20 to 52Mhz for high speed cards, we could have this speed even with plain old rs-mmc connector in N770. Needs nontrivial kernel modification of course :-)

Nokia is touting their new N95 superphone as "It's what computers have become."

Ah, so what is the 770?

Five new Nokia phones introed in 7 days. All using miniSD.

Is this a hint we can look forward to a 770 2.0? This or next year?

As for RS-MMC, J&R carried (in-store; I don't look on their site) 256MB, 512MB, and 1GB. Now all they have is 128MB! Yeesh.

Small correction: not miniSD but microSD.

Oops! No pun intended there, either, eh?

Yes, microSD. The teeny one that can be accidentally inhaled! (It's also used in the Sandisk Sansa e2xx players.)

Jaysus. Nokia has been pregnant and is now birthing a ton of phones! Three new music phones today. All *not* using RS-MMC...

Is the Internet Tablet division near labor?

Interesting. How do you like it? It seems not even prudent to get card reader built-in to computer any more since it likely to have slower transfer spped than this device.

I'm still waiting for it. It was out of stock and I didn't find alternative. I hope it will arrive tomorrow.

As for N770 speed - sad thing is that N770 USB connection seems to use only USB 1.1 speed and it looks like hardware limitation i.e. the USB chip is in fact 1.1. Looks like they corrected it in technical specifications http://europe.nokia.com/A4145105 since I asked. The '(with speeds up to 12Mbps)' part wasn't there last week. So you can't use N770 as fast usb card reader.

The limitations of 770 in transferring file through MMC or USB interface is unfortunate. Remarkable that wireless is the fastest way to transfer a file.

I am having trouble finding other MMC 4.1 readers. An internal (to PC) reader would be OK for wiFi transfer to 770, but typically only the USB dongle type readers give out their specs.
