Top iPod Touch/iPhone apps of the Month [for the broke college student IMHO] (all available free at the App Store, not Cydia, so no jailbreaking needed)

• Reference:
• The Weather Channel app contains current, hourly, 36-hour, and 10-day weather forecasts, which surely kicks the native Yahoo! weather app far, far away in my radar.
• Calendar: I'm inclined to have push notifications and support for Google Calendar, as outlined here but I'm open to other calendar apps that are easily syncable across platforms (this would be all solved with a GCal app, but I still don't see such a thing.)
• Educational Entertainment:
• MissSpell: This is a simple and fun game where you guess whether words are spelled correctly or not.
• Mobile Rice is sort of a questionnaire game where they ask you to define a word, or select a synonym.
• Word Lite: Haven't tried this one yet but it's supposed to be This is like a flashcard system of GRE-type words, which I need to learn quickly if I plan to apply to grad school in the near future. It offers 3 modes: studying, self-quiz, and testing. It's a very thorough system to ensure a painlessly easy way of hammering words into your memory. It comes with 26 words.
• Read It Later: Select webpages in Safari to read while offline/with no Wifi connection. I tried e-mailing myself some PDFs (because converting the PDFs to images or using FileZilla to mess around with the IP addresses of the PDFs seem to time-consuming for me) in Gmail and opening those to save them later with the 'Read It Later' bookmarklet, but that didn't work. It will work with regular web pages though. After you save the pages, go to this app to retrieve your saved pages to view offline.
• Productivity:
• Documents (developed by SavySoda) will let you download all your Google Docs to edit them and then upload them again to the Google Docs server. Beats the Google Mobile Apps/Google Docs mobile site which don't let you edit anything.
• Evernote lets you access and create notes
• fring lets you IM all your Skype, GTalk, MSN, Yahoo, AIM buddies. If you own a pair of earbuds with a built-in microphone or just a 3.5mm iPod-compatible microphone, you can make calls to your buddies. I use Skype 24/7 so this app is essential for me.
• Reqall can be your second brain where you store lists and to-do's. The app will let you edit documents offline. Read more about the most useful note app I have found here. 

 This list may change to reflect newly discovered gems in the App Store.
