Here are some Symbian S60 V5 apps that i use:
Soundhound: Way better than Shazam. You can even sing the songs to it and it would identify them.
Socially: One of the best symbian apps. It manages your Facebook and twitter account. Once you sync the phone contacts to online contacts it owuld automatically update the Contact Image on phone by fetching it from online account. It also adds a reminder for every birthday of your Facebook friend on your calender(saves a lot of time). Thats not all, whenever someone updates his status id you get a flash sms like notification on your phone. And when one of your friend calls his latest status update is displayed on the top of screen along with his pic.
Pixelpipe: Way better app than the Share Online. First it is free
, second it doesnt require you to log in with every online account where you wanna upload the pics or videos. Here you just create a pixelpipe account and add any number of online accounts to pixelpipe account.
When you are uploading a pic using share online, pic has to uploaded multiple times due to multiple accounts. Thus increased data cost.
In Pixelpipe, image would be uploaded to pixelpipe account once and from there it would be uploaded to all the other online accounts. Thus it reduces cost significantly.
Nokia Situations: Great app for college/school students. I guess everyone has had his share of bad luck when his phone wasn't silent and rang in class during lecture. This app helps us to avoid those situations. You can define conditions for phone to go silent and then come back to general profile.
These conditions are : Day of the week,time,network,gps,wifi,.
Now my phone automatically goes silent at 9 am and return to general at 5pm during weekdays. It goes offline at 1am so that i wont be disturbed and returns to general at 6 am.
Screensnap: As the name suggest, you can take screenshots of your phone's screen using this.
