I've been searching thru this forum and the web, but I couldn't find the answers...I'm not saying that do not exist, I've just not found them...

1- After playing a video, I always receive a message pop up, asking me: Would you like to delete "video_name" to conserve space? Keep or Delete
Is there any way to avoid this option?

2- When the phone is in stand by, and you receive a call, you finish the call and the phone returns to stand by status. But when you unlock the phone, you're taken to Contacts or Recent Calls depending on if the last call was taken or not (I think).
Wouldn't be better to be taken to the springboard? Is it possible?

3- I'm using Installer.app and in the bottom of the screen app I can see a text: "Space Available: 89,4 Mb". It decreases by downloading things.
What's this space related to? iPhone capacity or Installer free download quota?

Best Regards,

item 1 - doesn't happen any more if you upgrade to 1.1.1 firmware.

item 2 - good point, don't think anything exists on this yet

item 3 - I believe it is OS space. It approx halves on upgrading to 1.1.1, but that's still more than enough.

Hope that helps!
