I'm using the default calendar that came with the phone, and over time it's started to get really really slow in loading all the entries.
It's linked with my google calendar, and I don't know how to edit it, so it only shows lets say the last month in the past and month in the future calendar entries, so it doesn't have to load up the entire calendar. Hopefully that could speed it up. Or whether I should use a different application altogether? I'm not sure what's causing the problem.
