Expandable Storage via microSD
Microsoft supports expandable storage on Windows Phone 7 devices. If an OEM chooses to do so, it can implement a microSD card slot for additional storage. This is similar to what Google allows with Android, however the similarity ends here.
Windows Phone creates a JBOD span across your internal NAND and any NAND on microSD. It’s all treated as one contiguous address space, like a large hard drive or SSD. The benefit is you don’t have to manage where you put your apps, music, movies or photos. The downside is you can’t just remove/replace the microSD card in your phone.
The OS is obviously stored in a known location, however data is written linearly across both internal and microSD NAND. Your phone will still boot if you remove or swap out the microSD card, but you’ll be greeted with an error.
If you remove the card and attempt to read off of it on your Mac/PC you’ll quickly realize that you can’t. By removing the card you effectively break the file system. Microsoft provides you with a couple of other options to get data to/from the phone (which I’ll get to later) so you don’t have to rely on swapping microSDs.
You aren’t stuck with that original microSD card however. If you do a factory restore with a new microSD card installed the OS will format across it and you’ll be good to go. Obviously you’ll have to re-download all of your apps and sync all of your files but it does work.

I find it amusing that for a 'phone' there is often little to no discussion on call quality, reception, and ability to maintain connection in a difficult environment. We know that all phones are not equal on that score...It's like you don't expect people to actually make phone calls.

Making phone calls with your smart phone is just so passe.strikeback03 - Friday, October 22, 2010 - link
They said they have reviews of the actual phones coming, that is the type of info that would be in a review of the phone, not the OS.thartist - Thursday, October 21, 2010 - link

The lack of "change on the fly" micro SD is a deal killer for me.It's a shame too, because I really like everything else about this phone.

Curious: Why do you need such a feature?softdrinkviking - Friday, November 5, 2010 - link
whoa, i don't know if anyone else, or even you will get back to reading this but...i use SD cards to store music on. i have a situation where i can't always sync with my home pc very often, and i can't always carry around a laptop, so bringing along a handful of different SD cards with a variety of tunes has been important to me.
what i'd really like is for card-swapping to get more convenient, like in cameras.

In your review you guys say the LG Optimus 7 has a MicroSD slot that we can expand on, yet nowhere else does it say that on the web. Can you verify this? If it does than this phone is a clear winner for me, It's also avail in Canada btw. I'd hope we're just as important as Asia and Europse but I suppose were not haha.softdrinkviking - Friday, October 22, 2010 - link
the trick is that the microSD card gets treated like part of the built-in memory, and you cannot replace it without completely erasing your phone and starting over.so you basically have to choose a single SD card and stick with it, there is no changing on the fly like in android phones.

Wasnt really my question but thanks.But still unanswered is, I dont think LG Optimus 7 has a microsd slot, Engadget just reviewed it and stated it doesnt have a memory slot. Can you guys confirm this?
