my little brother anton told me about this:
when you’re viewing the calendar in “week” or “month” mode (you’re pretty much stuck in “today”), you can use the following number keys to navigate quicker:
| 1 … previous week | 3 … next week | |
| 4 … previous month | 6 … next month | |
| 7 … previous year | 9 … next year |
and pressing “c” (above number 3) will take you back to today’s entries.
this also works with sony ericsson’s t630, and presumably with all the other SE phones. and it’s a lot faster than choosing “more” – “select month”, and then scrolling to the one you want.
