Deleting photos from the device does not free up its memory. I accidentally filled up my remaining 3GB with burst photos and I was told I was running out of space. I deleted all the burst photos I took but my available capacity did not go back up. I'm fact, it kept going down each time I viewed it in About, going as low as 0 bytes and as high as 300MB. I then proceeded to delete every single photo on my phone but the available capacity did not go back up. I have 0 photos now but in About it shows I still have 543 and I do not have anywhere near the 3GB I originally had before taking all those burst photos. The photos tab is also missing in iTunes, so I can't try and erase them by syncing with a folder on my computer. Terrible glitch, I hope beta 3 fixes this. I should have like 4GB free right now after deleting every single photo I had on my phone.
