Sounds like PEBKAC to me. Tap the phone icon, it takes you right to the dialer. enter the number you want to call.
Tap the contacts icon, it takes you to the contact list. find the contact you want call tap on it, then click the number you want to call.
Or if you find that too tedious - just tap on the voice search icon and say "call xxxx."
How can it get any simpler than that?
It took me a few weeks to finally learn how to un-filter / filter my contacts
list. Up until that point I was tearing my hair out because I would add
contacts, but they wouldn't show up in 'Contacts' and they would be 100%
un-searchable on the phone (even though they would show up as a contact
in the 'Call Log' if the person called me

).
To make it even worse, on a GOOGLE phone mind you, (apparently) I can
not search the emails from my exchange account in "Mail"

So
having "lost" these contacts, the easy recovery would have been a quick
search for an email from that person with their signature, but nope, no
search, global or otherwise.
If you have the patience and/or time and/or curiosity it is a pretty good
phone OS (it's what I always wanted out of Symbian and WinMo5 3+ years
ago), but yeah, it ain't always easy or intuitive. Thankfully the guys on the
Android forums are usually pretty good at helping you work through these
issues when they come up.
An issue that still plagues me with no apparent solution is that my N1 still
won't automatically connect to my secure home wifi network for some
unknown reason
